Reverse osmosis system (RO DTS 20) in 20-foot container – 100 m³/day – Suitable for seawater / wastewater

For sale is a robust and well-maintained Disc-Tube reverse osmosis system (RO DTS 20), installed in an insulated 20-foot container. The system was originally designed for seawater desalination and was used by the THW for 20 years. In fact, the system was only used during 2 disasters. The modules have been cleaned and preserved. All main components, such as the high-pressure pump and valves, have been replaced. The system is connected and operated once a quarter. It is also ideal for the treatment of industrial wastewater or brackish water – e.g., in contaminated site remediation, landfill leachate treatment, or process water recycling.

The reverse osmosis system can be used universally thanks to the disc tube technology and offers the operator real added value.
